Accounting Policies [Abstract]
Basis of Presentation	The accompanying condensed consolidated financial statements have been prepared in accordance with the accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and pursuant to the instructions to Form 10-Q and Rule 10-01 of Regulation S-X of the U. S. Securities and Exchange Commission (“SEC”) and on the same basis as the Company prepares its annual audited consolidated financial statements. The condensed consolidated balance sheet at June 30, 2023, and the condensed consolidated statements of operations, comprehensive loss, and changes in stockholders' equity for the three and six months ended June 30, 2023 and 2022 and cash flows for the six months ended June 30, 2023 and 2022 are unaudited, but include all adjustments, consisting of normal recurring adjustments the Company considers necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented. The results for the three and six months ended June 30, 2023 are not necessarily indicative of results to be expected for the year ending December 31, 2023 or for any future interim period. The condensed consolidated balance sheet at December 31, 2022 has been derived from audited financial statements, however, it does not include all of the information and notes required by U.S. GAAP for complete financial statements. The accompanying condensed consolidated financial statements should be read in conjunction with the audited financial statements for the year ended December 31, 2022 and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022 as filed with the SEC on March 30, 2023. The Company’s consolidated subsidiaries consist of its wholly-owned subsidiaries, Rockwell Transportation, Inc. and Rockwell Medical India Private Limited. The accompanying condensed consolidated interim financial statements include the accounts of the Company and its subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of the condensed consolidated financial statements in conformity with U.S. generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that may affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of expenses during the reporting period. Actual results could differ from those estimates.
Loss Per Share	Included within the weighted average shares of common stock outstanding for the three and six months ended June 30, 2023 and 2022, are 1,793,000 and 9,056,377 shares of common stock issuable upon the exercise of the pre-funded warrants (See Note 10), as the warrants are exercisable at any time for nominal consideration, and as such, the shares are considered outstanding for the purpose of calculating basic and diluted net loss per share attributable to common stockholders.The Company’s potentially dilutive securities include stock options, restricted stock awards and units, convertible preferred stock and warrants. These securities were excluded from the computations of diluted net loss per share for the three and six months ended June 30, 2023 and 2022, as the effect would be to reduce the net loss per share.
Adoption of Recent Accounting Pronouncements	Adoption of Recent Accounting Pronouncements The Company continually assesses new accounting pronouncements to determine their applicability. When it is determined a new accounting pronouncement affects the Company’s financial reporting, the Company undertakes a review to determine the consequences of the change to its consolidated financial statements and assures there are sufficient controls in place to ascertain the Company’s consolidated financial statements properly reflect the change. In June 2016, the FASB issued Accounting Standards Update ("ASU") 2016-13, "Financial Instruments - Credit Losses (Topic 326)," which introduced an impairment model that is based on expected credit losses, rather than incurred losses, to estimate credit losses on certain types of financial instruments (e.g., loan commitments). The expected credit losses should consider historical information, current information, and reasonable and supportable forecasts, including estimates of prepayments, over the contractual term. Financial instruments with similar risk characteristics may be grouped together when estimating expected credit losses. In addition, ASC 326 requires expected credit relates losses for available-for-sale debt securities to be recorded through an allowance for credit losses, while non-credit related losses will continue to be recognized through other comprehensive income. The Company adopted the new guidance, as of January 1, 2023, and it did not have a material impact on the Condensed Consolidated Financial Statements.
Revenue recognition	The Company recognizes revenue under ASC 606, Revenue from Contracts with Customers. The core principle of the new revenue standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The following five steps are applied to achieve that core principle: •Step 1: Identify the contract with the customer •Step 2: Identify the performance obligations in the contract •Step 3: Determine the transaction price •Step 4: Allocate the transaction price to the performance obligations in the contract •Step 5: Recognize revenue when the company satisfies a performance obligation Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by us from a customer, are excluded from revenue. Shipping and handling costs associated with outbound freight related to contracts with customers are accounted for as a fulfillment cost and are included in cost of sales when control of the goods transfers to the customer.
