Product Description

This Lactose Monohydrate secondary analytical standard is produced for use in identity and quantitative testing in pharmaceutical, excipient, and food and beverage analysis, where reliable traceability to a suitable primary reference material is required. Intended for routine quantitative applications, this standard supports the detection and measurement of sucrose as a potential foreign sugar, adulterant, or process‑related impurity in compendial, regulatory, and specification‑driven workflows.

Each lot is prepared, characterized, and value‑assigned using documented traceability to an appropriate primary reference standard, ensuring verified identity, assigned content, and excellent batch‑to‑batch consistency. This enables confident calibration, quantitative analysis, and ongoing quality control testing across diverse analytical methods. Comprehensive documentation, including a detailed Certificate of Analysis describing the traceability chain and value‑assignment approach, supports method validation, system suitability, and audit readiness.

Designed for analytical laboratories that demand precision, consistency, and regulatory confidence, this sucrose secondary standard delivers dependable performance for USP‑ and pharmacopeia‑aligned carbohydrate testing, as well as routine food and beverage testing applications requiring reliable traceable calibration.
