Analytical method information
The HPLC procedure specifies C18 (4.6 × 250 mm, 5 μm), methanol–water (43:57, v/v), flow 1 mL/min, detection at 250 nm, 30°C, 10 μL injection and external-standard calculation. The separate UV procedure measures absorbance in ethanol at 242 ±2 nm. These are different measurement procedures: a UV percentage must not be presented as an HPLC result. Request the full method and confirm reference-standard identity and reporting basis.
From specification to quotation
Send your target grade, quantity, intended use and destination. We coordinate specification questions and document requests with the source, then discuss sample arrangements and commercial terms for your review.
Final composition, packaging, storage, shelf life and destination-specific requirements are confirmed for the proposed material. A specification reference does not establish approval for every application or market.
