Potassio idrogeno ftalato standard - NIST-2185
Potassium hydrogen phthalate standard - NIST-2185
Certificato ISO 9001:2015 & ISO 14001:2015 · Fornitura a laboratori e industria dal 2000 · Certificato di Analisi (CoA) per ogni lotto
Potassium hydrogen phthalate (KHP) is a high-purity analytical standard primarily used for acid-base titrations to calibrate solutions like sodium hydroxide, ensuring accurate pH and concentration measurements. It serves as a primary standard due to its stability, non-hygroscopic nature, and precise stoichiometry. This NIST-traceable reference material (CAS 877-24-7) has a molecular formula of HOOCC6H4COOK and a molecular weight of 204.22 g/mol. It requires no special storage—store at ambient conditions—and carries no signal word for hazard classification. Molekula supplies Potassium hydrogen phthalate standard - NIST-2185 from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
