To be exact, you are requested to use our product No. for your ordering. Please contact your dealer, our export department or overseas offices for your quotation.
- Synthesis of reagents not listed in the catalog may be accepted.
Since many reagents have specific properties, no return of merchandise please.
- All reagents listed are of experimental and research use only.
- Many reagents and chemicals do not provide sufficient chemical information particularly about harmfulness.
Even if there is no indication of hazards and safety, please follow general rules for handling chemical substances.
Information on safety
The safety label and the Kanto Catalog provide the first source of information for the safe handling of reagents. Hazardous goods in the catalog are marked with hazard symbols according to the Japanese regulations and GHS. However anyone handling reagents should always observe following safety rules even if a label carries no hazard warning.
- Always ware eye protection; ware gloves whenever possible.
- Work in a well ventilated area.
- Avoid contact with skin, eyes and mucous membranes.
- Be sure to seek medical advice in the event of accident or feeling unwell.
The following hazard symbols are the standard symbols which should be used in the GHS.
May cause explosion exposed to heat, or spark.
|May cause ignition exposed to air, heat, or spark.
The pictogram indicates gases under pressure, which are contained in a receptacle compressed or liquefied. May cause explosion due to expansion if heated.
|May contribute to the combustion of other material.
May fatal due to the acute health hazards if swallowed, contacted, or inhaled.
|May cause corrosion to metals or skin in contact with metals or skin.
|May cause health hazards if swallowed, contacted , or inhaled in a short or long term.
|Cause health hazards by acute toxicity, skin irritation, eye irritation, skin sensitization, airways irritation, or anesthetic action.
|May have a harmful effect on the aquatic environment (an aquatic organism and its ecosystem) if released in the environment.
Product name conforms to the IUPAC compound nomenclature method, and it has made it the main name in consideration of idiomatic name etc.

Indicative formula & Molecular weight
For obvious products of the structure, we display molecular formulas or molecular formulas followed by molecular weight based on the atomic weight table.
Physical property value
Basically, it describes physical property values such as melting point, boiling point, specific gravity etc. by information of literature etc. please note that the description may be different for each product.
Purity & Content
The purity / content indication of each products are in principle weight percentage (w/w %), in other cases it is indicated as v/v %, w/v % etc. However, for Acros products, the standard value is indicated only when there is an "＞" mark in the purity display column. Purity indication without a "＞" mark is a representative value having an allowable range. Please note that many ACROS products display purity by representative value.
