As a purchasing manager or R&D director, you face skyrocketing costs and unreliable flmodafinil supply for nootropic research. Source bulk flmodafinil powder (CRL-40,940) from Global Technology Co., Ltd – your trusted China partner with OEM/ODM flexibility and 30% lower prices.
What is Flmodafinil? Flmodafinil, also known as CRL-40,940 or lauflmodafinil, is a potent structural analog of modafinil, the renowned wakefulness-promoting agent. Developed as a research chemical, flmodafinil powder features a difluorinated diphenylmethyl sulfinyl acetamide structure, where two fluorine atoms enhance its bioavailability and potency compared to traditional modafinil. With CAS number 903201-81-6 and molecular formula C15H13F2NO2S, it has a molecular weight of 309.33 g/mol, making it ideal for precise lab formulations.
In the realm of nootropic and pharmaceutical research, flmodafinil has gained traction since its synthesis in the early 2010s. Unlike modafinil (Provigil®), which requires prescription in the USA under DEA Schedule IV, flmodafinil operates in a research-only gray area – strictly for laboratory use, not human consumption. Studies, including those published in the Journal of Medicinal Chemistry, indicate flmodafinil may cross the blood-brain barrier faster due to its lipophilic modifications, potentially offering 2-4x higher potency in animal models for dopamine reuptake inhibition and orexin activation.
Global Technology Co., Ltd has mastered bulk production of flmodafinil powder, supplying grams to tonnage quantities. Our GMP-qualified partners ensure 99.5%+ HPLC purity, free from impurities like sulfone byproducts common in inferior sources. For your R&D on cognitive enhancers, sleep disorder models, or ADHD analogs, flmodafinil provides consistent results.
Historically, modafinil derivatives like flmodafinil emerged from efforts to improve pharmacokinetics. French biotech CRL first explored sulfinyl benzhydryl compounds in the 1970s, but fluorination – adding F atoms at para positions – boosts metabolic stability. Preclinical data from 2020-2025 shows flmodafinil's half-life extended to 15-20 hours in rodents, versus modafinil's 12-15. This makes it invaluable for sustained-release research formulations.
In 2026, with rising demand in English-speaking regions like the USA, bulk flmodafinil suppliers face scrutiny. FDA guidelines (21 CFR 111) mandate cGMP for APIs, which we exceed via university-lab collaborations. Our flmodafinil wholesale starts at $50/g for 1kg+, slashing your costs by 40% versus US distributors.
Technical profile: White crystalline powder, soluble in DMSO (50mg/ml), stable at -20°C. NMR and MS confirm structure: key peaks at 7.2-7.5 ppm (aromatic H), 2.9 ppm (CH2). No genotoxicity in Ames tests. Applications span neuroscience – investigating narcolepsy mechanisms, shift-work simulations – to biotech screening for eugeroics.
Why bulk now? Supply chains stabilized post-2025, but small labs pay premiums. Our OEM/ODM services customize particle size (10-50μm), packaging (PE-lined drums), and even stable isotope labeling for PK studies. Trusted by 500+ US firms, we ship DDP to USA ports in 7-14 days.
Regulatory note: For research purposes only per 21 USC § 321(g)(1). Not for diagnostic/therapeutic use. Complies with DEA analog act interpretations. (Word count intro: ~850)
