Modafinil is a synthetic compound combining a diphenylmethyl group with a sulfinyl-acetamide moiety, developed as a wakefulness-promoting agent with a mechanism distinct from traditional stimulants. It’s the active ingredient in an FDA-approved medication used to manage excessive sleepiness associated with narcolepsy, obstructive sleep apnea, and shift-work sleep disorder, and its use is regulated as a Schedule IV controlled substance due to its stimulant-adjacent pharmacology.
Sarchem’s research-grade material, where appropriately licensed, supports pharmaceutical R&D activities: reference-standard work for analytical method development and identity/purity confirmation, and pharmacokinetic or formulation-development research into wakefulness-promoting mechanisms. Given its controlled-substance status, all handling, storage, and transfer must comply with applicable DEA Schedule IV requirements in addition to standard chemical-safety practice.
*No GHS hazard classification data was available from the reference source used for this product. Given its pharmacological activity and controlled-substance status, treat with the same handling rigor as other CNS-active pharmaceutical reference materials, and consult your own SDS and compliance team.*

As an analytical reference standard and pharmacokinetic/formulation-development research compound studying wakefulness-promoting mechanisms, where appropriately licensed under controlled-substance regulations.
Chemically the same active compound, but Sarchem's listing is a bulk research-grade chemical, not the finished, FDA-approved Provigil drug product — and both require appropriate regulatory authorization to handle (DEA registration for the bulk chemical; a separate approval pathway for the finished drug).
Sigma-Aldrich's own primary brand does not list Modafinil; the only available reference was a small third-party marketplace listing — consistent with this being a tightly controlled compound under DEA scheduling.
68693-11-8. (Sarchem's live page currently shows an invalid value, "24395956," which is not a valid CAS format — see the bug report at the top of this document.)
A COA/SDS would accompany any lot, but given its DEA Schedule IV status, fulfillment requires confirming appropriate registration on both sides of the transaction — please contact Sarchem directly to confirm compliance requirements before ordering.
