Supplied as a colorless to pale yellow liquid that may solidify at lower room temperatures, it possesses a characteristic sweet, warm, and slightly vanilla-like odor. Veratrole serves as a critical intermediate in the flavor and fragrance industry and finds applications in pharmaceutical and agrochemical

Reagent Sulfuric Acid 96.5% (typically conforming to ACS specifications) is characterized by high purity and very low levels of metal impurities and residue. Its main applications include: 1. Laboratory & Analytical Chemistry General Reagent : Used to prepare dilute sulfuric acid, standard solutions, and for titrations, pH adjustment, and acidification. Sample Digestion : Utilized in COD (Chemical Oxygen Demand) testing, Kjeldahl nitrogen determination, and trace metal

Reagent Sulfuric Acid 41% is a high-purity acid solution (typically meeting ACS specifications) that delivers moderate acidity with low viscosity, minimal fuming, and very low heat generation upon dilution. This specific concentration is particularly convenient for preparing lead-acid battery electrolyte, performing analytical procedures that require precise moderate acid strength, and carrying out mild chemical transformations where aggressive charring or dehydration must be

Reagent Sulfuric Acid 94% is a high-purity grade (often meeting ACS or similar specifications) with slightly lower concentration than 96–98% grades, making it convenient for applications requiring precise dilution or moderate acidity. Its main uses are: 1. Laboratory & Analytical Chemistry General Reagent: Preparation of diluted acid solutions, pH adjustment, and standard acid titrations. Sample Digestion: Used in COD (Chemical Oxygen Demand) and Kjeldahl nitrogen determinati

Reagent Sulfuric Acid 98% is a high-purity acid (typically ACS grade) with maximum concentration before fuming, offering strong acidity, exceptional dehydrating power, and low impurity levels. It is a fundamental laboratory and industrial reagent. 1. Laboratory & Analytical Chemistry Standard Solution Preparation : Primary acid for preparing precise volumetric solutions and titrants. Sample Digestion : Used in COD (Chemical Oxygen Demand), Kjeldahl nitrogen, and heavy metal
