As a specialized active ingredient for bone metabolism, vitamin K2 (CAS 863-61-6) is more suitable for pharmaceutical development and large-scale production than long-chain vitamin K2 (CAS 2124-57-4). It provides stable and compliant support for osteoporosis and bone health drug programs. Often used with calcium and anti-osteoporosis agents, it is a safe and reliable raw material for bone health therapies. As top China vitamin K2 manufacturers, we ensure stable supply for clients looking to purchase vitamin K2.
Product Features
Vitamin K2 (CAS 863-61-6) appears as pale yellow to yellow crystalline powder with a clear chemical structure, excellent purity, and strong batch consistency. Compared with CAS 2124-57-4, it has a shorter molecular chain, more concentrated tissue targeting, and outstanding pharmaceutical properties that meet raw material standards for formulations. We support customized vitamin K2 to meet diverse development needs.
This raw material features clear action targets, mainly participating in osteocalcin activation and bone metabolism regulation, with rapid bioavailability and definite metabolic pathways. Compared with long-chain vitamin K2, it functions more directly in bone-related applications and offers good compatibility, satisfying clinical formulation development requirements.
Produced under standardized manufacturing processes, the product undergoes strict full-process quality control with stable crystal form, low impurities, and reliable properties. Different from the long metabolic cycle of CAS 2124-57-4, this product metabolizes faster and allows flexible dosage design, complying with pharmaceutical safety requirements.
With stable physical and chemical properties, the product maintains excellent quality under proper storage and is suitable for R&D, scale-up, and mass production. With precise performance and reliable quality, it provides stable and efficient support for bone health formulation projects. We have ample vitamin K2 in stock for fast delivery.
Full-Cycle Quality Control & Consistent Quality
Full-process quality control is implemented from raw material selection to finished product delivery. Each batch of vitamin K2 (CAS 863-61-6) is rigorously tested to ensure stable purity and properties, with better consistency than general long-chain vitamin K2 (CAS 2124-57-4), meeting high pharmaceutical standards.
Production follows standardized operating procedures with real-time monitoring of key process parameters, effectively controlling impurities and crystal form variations. Compared with CAS 2124-57-4, this product shows more stable quality in large-scale production and provides a reliable foundation for formulation development.
A complete quality traceability system enables full tracking from production to storage and transportation, effectively ensuring stable product quality. Supported by strict quality control, it exhibits outstanding stability and long-lasting activity, superior to conventional long-chain vitamin K2 products.
We continuously optimize quality control protocols and conduct multi-dimensional testing to comply with global standards. With stable and reliable quality, it is more suitable for pharmaceutical applications than CAS 2124-57-4, providing strong assurance for long-term customer cooperation. As a professional China vitamin K2 factory, we guarantee consistent quality.
