What is Vitamin B6 Pyridoxal?
Pyridoxal (CAS 66-72-8), also known as Piridoxal, is one of the three primary forms of vitamin B6 alongside pyridoxine and pyridoxamine.
Where is Vitamin B6 Pyridoxal used?
- Pharmaceutical manufacturing: starting material or reference standard for B6-related active pharmaceutical ingredients
- Nutritional supplements: more bioavailable or reactive B6 form than pyridoxine hydrochloride
- Biotechnology and cell biology research: study of transaminase activity, enzyme kinetics and cofactor-dependent metabolic pathways
- Animal feed and veterinary nutrition: B6 form differentiation in specialised feed premixes
- It serves as a direct precursor to pyridoxal-5-phosphate (PLP), the coenzyme involved in enzymatic reactions.
Commercial specifications
- Grades meet purity requirements of laboratory and API synthesis applications
- Packaging from small laboratory quantities to bulk industrial procurement
