For procurement specialists and product developers in the pharmaceutical and food additive sectors, sourcing high-quality L-Hydroxyproline is a critical step. This amino acid, identified by CAS number 51-35-4, is essential for specific manufacturing processes, notably in the creation of antiviral drugs and as a functional food ingredient.

When considering where to buy L-Hydroxyproline, several factors are paramount. Firstly, the product's appearance and physical state are indicative of its quality; a white fine powder is the standard for pharmaceutical and food grade L-Hydroxyproline. Secondly, purity levels are non-negotiable, with >99% purity being the benchmark for most applications. This level of purity ensures that the L-Hydroxyproline will perform as expected in sensitive chemical reactions or food formulations.

Certifications play a crucial role in verifying the quality and compliance of L-Hydroxyproline. Buyers should look for manufacturers holding ISO 9001 for quality management, KOSHER and HALAL for dietary compliance, and GMP for good manufacturing practices. These certifications provide assurance that the L-Hydroxyproline has been produced and handled under rigorous standards. Test standards such as AJI and USP further validate the product's suitability for specific markets.

The application of L-Hydroxyproline spans from being a key pharmaceutical intermediate, particularly in the synthesis of drugs like azanavir, to its use as a sweetener in the food industry. Its role as a sweetener is gaining traction as consumers and manufacturers alike seek more natural ingredients. Understanding these applications helps buyers identify the precise grade and specification of L-Hydroxyproline they require.

When establishing a relationship with a supplier, it is important to consider their reliability, delivery times, and customer service. Factors such as packaging (e.g., 25kg/Drums) and shelf life (2 years) are also vital considerations for inventory management. By thoroughly evaluating these aspects, businesses can ensure a consistent and high-quality supply of L-Hydroxyproline, supporting their ongoing production and product development efforts.
