Description

Mebendazole High Quality Competitive Price 99% Mebendazole Powder CAS 31431-39-7

Mebendazole is a compound with the chemical formula C16H13N3O3. It is a broad-spectrum anthelmintic and has significant effects in killing larvae and inhibiting the development of insect eggs. Observation of ultrastructure shows that microtubules in the cytoplasm of the insect's membrane cells and intestinal cells undergo degeneration, leading to the aggregation of secretory granules in the Golgi apparatus, resulting in transport blockage, cytoplasmic dissolution and absorption, complete cell degeneration, and insect death

White Amorphous Powder
Mebendazole is a white to slightly yellow powder. Pleasant taste. Practically water insoluble. (NTP, 1992)|Solid
Mebendazole is a white to slightly yellow powder. Pleasant taste. Practically water insoluble. (NTP, 1992)|Mebendazole is a carbamate ester that is methyl 1H-benzimidazol-2-ylcarbamate substituted by a benzoyl group at position 5. It has a role as an antinematodal drug, a tubulin modulator and a microtubule-destabilising agent. It is a member of benzimidazoles, a carbamate ester and an aromatic ketone. It derives from a hydride of a 1H-benzimidazole.|Mebendazole is an Anthelmintic.|Mebendazole is an anthelmintic agent used commonly for roundworm (pinworm and hookworm) infections, trichinosis, capillariasis and toxocariasis and other parasitic worm infections. Mebendazole when given for prolonged periods in high doses has been associated with elevations in serum enzyme levels, and rare instances of acute, clinically apparent liver injury have been linked to its use.|Mebendazole is a synthetic benzimidazole derivate and anthelmintic agent. Mebendazole interferes with the reproduction and survival of helminths by inhibiting the formation of their cytoplasmic microtubules, thereby selectively and irreversibly blocking glucose uptake. This results in a depletion of glycogen stores and leads to reduced formation of ATP required for survival and reproduction of the helminth. This eventually causes the helminths death.|A benzimidazole that acts by interfering with CARBOHYDRATE METABOLISM and inhibiting polymerization of MICROTUBULES.

Reactive Group:

Carbamates

Reactivity Profile:

MEBENDAZOLE is a carbamate ester-amine. Amines behave as chemical bases. Carbamates are chemically similar to, but more reactive than amides. Like amides they form polymers such as polyurethane resins. Carbamates are incompatible with strong acids and bases, and especially incompatible with strong reducing agents such as hydrides. Flammable gaseous hydrogen is produced by the combination of active metals or nitrides with carbamates. Strongly oxidizing acids, peroxides, and hydroperoxides are incompatible with carbamates.
